Abstract
Since 1959 bacteria in urine of cystitis and pyelonephritis (acute) have been cultivated on urological division. Gram negative bacilli were found generally over 80 per cent in culture and Escherichia Coli were mostly. But in cystitis which were infected owing to leave catheter after the operations of bladder and prostate, Klebsiella, Citrobacteria, Proteus Pseudomonas and A. cloacae were found more than Escherichia Coli.
Simple cystitis and acute pyelonephritis could be treated by sulfamethizol or an antibiotics, but in cystitis due to retrograde infection mulitiple-antibiotics resistant bacilli were frequently found and only sensitive to Colimycin and Kanamycin. These tendency become remarkable year by year.
The multiple-antibiotics resistant bacilli are not only Klebsiella, Proteus, etc., but also Escherichia coli recently.
The chemotherapy for the urinary tract infections become difficult, because more multiple-antibiotics resistant bacilli have been increasing recently.
